The Lions' pass offense has been impressive in their 4-0 start, but what about that 30th-ranked running game? This week's Monday Night Football column looks at how the disparity between the two raises red flags about Detroit's Super Bowl prospects.

Analysis of the surprising 3-1 Titans shows a team very similar to the Titans team that went 13-3 in 2003: strong passing and defense overcoming a stagnant running game. But since Matt Hasselbeck is unlikely to continue playing at a superstar level, the onus is on the defense to keep the team in the AFC South race.

Indianapolis' season is basically over at this point with Peyton Manning gone, but the Colts have also sustained a number of other injuries this season. This is not a one-year trend in the slightest -- the Colts lead the NFL in Adjusted Games Lost over the past five seasons. Why is that?
